It is an inflammatory parasitic infection caused by Trypanosoma cruzi, a parasite present in the excrement of the triatomine or kissing bug, affecting anyone and causing cardiac and digestive complications that can be extremely serious.
The way this parasite can enter the body is through the insect bite, through the mouth and eyes, or a wound or scrape.
You can also become infected by eating raw food exposed to contaminated insect feces, receiving a blood transfusion, or organ transplant from an infected person, or having contact with infected wild animals.
Once the parasites enter the body, they multiply and spread rapidly. Triatomines usually hide during the day in the walls, cracks, and ceilings of rustic houses, coming out at night to feed on the blood of animals and humans while they sleep. They generally inhabit some Central American regions, including Mexico and South America.
The symptoms can appear suddenly for a short period or evolve into a chronic condition, in which it is no longer possible to get rid of the parasite, but only to control it.
The condition’s magnitude varies depending on the case and can be mild or severe.

In addition to analyzing your symptoms and clinical history, the doctor will perform a physical examination and request a blood test to confirm the diagnosis. If you have Chagas disease, your doctor will probably order additional diagnostic tests such as an echocardiogram, electrocardiogram, endoscopy, chest, and abdominal X-rays, which help determine the stage of the infection and if you have heart and/or digestive damage.
Pharmacological treatment consists of eradicating the parasite and controlling specific symptoms by taking various medications. But if the disease has progressed to the chronic phase, the treatment will consist of controlling the symptoms and attending to the cardiac or digestive complications presented, either with drugs or with surgery.
